Performance:

The three offset Design include:

1. Deviation from the center of the pipeline

2. Off center of sealing surface

3, inclined cone

When the valve is opened, the butterfly plate and the valve seat are in instant contact when they are closed, and the butterfly plate eccentricity 1 and eccentricity 2 are used to quickly separate from the valve seat, which reduces the wear of the seal pair, the friction torque is small, and the opening is flexible. The eccentric cone surface 3 enables the butterfly plate to pass through the inner hole of the valve seat when the valve is opened or closed to achieve contact sealing. In addition, the radius of rotation of the cone-shaped butterfly plate is greater than the rotation radius of the contact position of the sealing pair, so the butterfly plate will appear tighter and tighter when the valve is closed.

 

Application:

It is used for regulating flow and carrying fluid in industrial pipelines such as electric power, petrochemical industry, water supply and drainage, and municipal construction.
